This file contains various supplementary material for the revision of “Transparency and Deliberation”.  Only fomc_techincal_appendix and perhaps topic_table_raw are intended for online publication.

The files are as follows:

collocations_bi.csv: This lists the frequency of bigrams tabulated in the FOMC transcripts during the Greenspan Chairmanship according to the method described in section 4.2.  Those that appear 100 times or more are represented as a single term.

collocations_tri.csv: As for collocations_bi.csv, but for trigrams.  Those that appear 50 times or more are represented as a single term.

fomc_technical_appendix.pdf: This contains all technical details for LDA, most of which has now been removed from the manuscript.

PlaceboTablesFull.pdf: As described in the penultimate paragraph of section 5.3, one concern with our placebo test is that we work with a reduced sample size.  These tables report the placebo results if we use all observations during our placebo window.

topic_table_raw.csv: We designed figure 2 in the revision to represent the topics in an accessible and compelling way, but the raw data are also informative.  This file lists the probability of the top 50 terms in each topic.
